[Freeswitch-users] Bridging dingaling to sofia

[Kieran O'Loughlin]

Hey all,

I've been playing around with trying to bridge dingaling to sofia for some
time now.  I've had some success.

1) I can call to googletalk using a local sip registration
2) I can call to googletalk using a remote sip registration
3) I can call from googletalk to a local sip registration
4) I can call from a local sip registration to a remote sip registration

In case my terminology is bad when I say local registration I mean that the
soft-phone is registered with freeswitch.  When I say remote sip
registration I mean that the soft-phone is registered with my standard SIP
provider.

The problem is if I call from googletalk and attempt to bridge the call to
my remote sip provider the call rings, but there is no audio.

I've tracked through the console and here is the piece that's different.
This piece never shows up if I attempt to bridge the call to a remote sip
registration.  I copied this from the console when bridging to a local sip
registration.

The weird thing is that if I call the same extension in default_context.xml
using a sip phone registered locally it bridges without any problem to the
remote sip registration.

Can anyone please help with this?  I've been battling it for a long time
now.  I've learned a lot which is good though :-).

By the way I just downloaded the last svn version today, so I couldn't be on
a more recent version :-)  Also if this isn't the best place to address this
type of question if anyone could point me in the right direction that would
be greatly appreciated.

Thanks for any help.

Kieran.
